This study seeks to investigate the impact of diet and cannabis on penile health in an animal model.
To determine the effects of diet and oral cannabis extract on fibrosis and oxidative stress within the corpora cavernosa of mice.
This is a pilot animal study in which groups of 2-month old C57BL/6J male mice were fed a normal chow diet (NCD) or high-fat diet (HFD) daily and treated with or without either MJ or THC extract for 2months. After euthanization, mouse penises were isolated and processed for immunohistochemical studies to determine (i) smooth muscle cell to collagen content, (ii) myofibroblast proliferation, and (iii) anti-oxidative activity.
Quantitative assessment of immunohistochemical markers of fibrosis and oxidative stress within the corpora cavernosa of mice fed a high-fat diearijuana Promotes the Development of Fibrosis in the Mouse Corpora Cavernosa. Sex Med 2021;9100312.
HFD combined with oral MJ extract led to structural alterations in erectile tissue that are associated with accelerated corporal fibrosis. However, the addition of THC to the diet did not exacerbate histological changes within the corpora. Further studies are warranted to elucidate the discrepant effects between MJ and THC in order to optimize the therapeutic potential of cannabis and minimize its adverse effects on penile health.

Sex Med 2021;9100312.Although an association between erectile dysfunction (ED) and lower urinary tract symptoms (LUTS) has been suggested, it was not clarified whether LUTS developed before ED or vice versa.
To clarify whether LUTS develop before ED or vice versa and which symptoms predicted the onset of the other condition in a longitudinal community-based study.
We conducted a longitudinal community-based study on LUTS and ED in aged Japanese men. A follow-up study was conducted to determine their longitudinal changes of LUTS and ED after 15years. Erectile function was evaluated using a validated questionnaire. LUTS were evaluated based on the International Prostate Symptom Score, quality of life index, and prostate volume.
We evaluated the baseline symptoms among the participants who had LUTS and ED in the follow-up survey and what prior symptoms could predict the onset of the other condition using the data from a long-term longitudinal survey.
A total of 108 men were enrolled in this study. Of the 47 men having bothg-term longitudinal study. Nocturia may be a predictor of subsequent ED. Matsuda Y, Kobayashi K, Fukuta F, et al.

Beyond the so-called yield-rate trade-off, resource allocation models, which focus on assigning different functional roles to the limited number of enzymes that a cell can support, offer a framework to interpret the inefficient substrate use by microorganisms. We review here relevant examples of substrate conversions where a significant part of the available energy is not utilised and how resource allocation models offer a mechanistic interpretation thereof, notably for open mixed cultures. Future developments are identified, in particular, the challenge of considering metabolic flexibility towards uncertain environmental changes instead of strict fixed optimality objectives, with the final goal of increasing the prediction capabilities of resource allocation models. Finally, we highlight the relevance of resource allocation to understand and enable a promising biorefinery platform revolving around lactate, which would increase the flexibility of waste-to-chemical biorefinery schemes.Favorable interspecies associations prevail in natural microbial assemblages. Some of these favorable associations are co-metabolic dependent partnerships in which extracellular electrons are exchanged between species. For such electron exchange to occur, the cells must exhibit electroactive interfaces and get involved in direct cell-to-cell contact (Direct Interspecies Electron Transfer/DIET) or use available conductive mineral grains from their environment (Conductive-particle-mediated Interspecies Electron Transfer/CIET). This review will highlight recent discoveries and knowledge gaps regarding DIET and CIET interspecies associations in artificial co-cultures and consortia from natural and man-made environments and emphasize approaches to validate DIET and CIET. Additionally, we acknowledge the initiation of a movement towards applying electric syntrophies in biotechnology, bioremediation and geoengineering for natural attenuation of toxic compounds. Next, we have highlighted the urgent research needs that must be met to develop such technologies.Microbial communities are complex but there are basic principles we can apply to constrain the assumed stochasticity of their activity. By understanding the trade-offs behind the kinetic parameters that define microbial growth, we can explain how local interspecies dependencies arise and shape the emerging properties of a community. If we integrate these theoretical descriptions with experimental 'omics' data and bioenergetics analysis of specific environmental conditions, predictions on activity, assembly and spatial structure can be obtained reducing the a priori unpredictable complexity of microbial communities. This information can be used to define the appropriate selective pressures to engineer bioprocesses and propose new hypotheses which can drive experimental research to accelerate innovation in biotechnology.
